FREDERICK R. JONES, OF BUFFALO, NEW YORK, ASSIGNOR TO BUFFALO CO-OPERATIVE STOVE COMPANY, OF BUFFALO, NEW YORK, A CORPORATION OF NEW YORK.

INCINERATOR.

Specification of Letters Patent.

Patented July 29, 1919.

Application filed April 29, 1915. Serial No. 24,713.

To all whom it may concern:

Be it known that I, FREDERICK R. Jones, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Incinerators, of which the following is a specification.

My invention relates to improvements in incinerators or crematories, and more particularly to apparatuses so termed for burning or destroying garbage and refuse accumulated in households, restaurants, hospitals, etc.

One of the objects of my invention is to supply an apparatus of this type with means co-temporarily store garbage and refuse in a sanitary manner prior to consuming the same by fire, and to provide means for consuming the garbage and refuse by fire in a manner to eliminate smoke and odor.

Another object of my invention is the provision of an apparatus of this type in which ventilation is provided for drying out garbage and refuse stored therein prior to incinerating.

Another object of my invention is to provide an apparatus of this kind with a receptacle for the garbage and refuse, and means to direct a sheet of live flame to apoint between said receptacle and the escape or drafi stack of the apparatus, into which all flame, smoke and gases from the refuse must pass and whereby the same are fully consumed.

Another object is to provide means whereby a uniform concentrated wall of fire is carried to the upper part of the apparatus and to introduce heated air and cause. the same to enliven said wall of fire. said wall of fire being situated in such relation to the escape .or draft stack of the apparatus and to the burning refuse that all smoke and gases escaping from the refuse must pass into the wall of fire in its course toward the stack and thus be consumed.

A further object is !to provide means whereby the rising smoke and gases from the refuse encounter cross currents of heated air and whereby said air and the smoke and gases are consumed at a point between the escape stack of the apparatus and the point at which said air commingles with saidsmoke and gases.

A further object is to provide means for temporarily checking or retarding the smoke in its passage toward the stack by subjecting it in its passage to cross currents of heated air, which causes the lighter gases contained in the smoke to separate and be consumed by the flames from a burner, thus assisting combustion and consuming the gases and smoke.

It further consists in providing a restricted passage for the escape of smoke and gases from the burning material and equipping said passage with a retarding hood to battle back excess smoke and to concentrate a live flame within the hood into which all gases and smoke rising from the burning refuse are drawn by thedraft created through the stack of the apparatus.

With these and other objects to be hereinafter described, the invention consists in the novel arrangement of features and in the construction and arrangement of parts "to be hereinafter described and particularly pointed out in the subjoined claims.

Reference being now had to the drawings in detail, similar numerals of reference refer to similar parts in the several figures,

- other suitable non-conducting material.

These wall members are spaced apart to provide an outer air chamber 22 and an inner air chamber 23, thus forming insulated walls.

The bottom wall is provided with a series of air inlets 24 which open into the outer air chamber 22 of the side and rear chambered walls and a series of openings 25 which open into the inner air chamber 23, thus admitting air to these chambers for purposes to appear hereinafter.

The top wall comprises a stepped rim 26 bolted or otherwise secured to the upper ends of the cast wall members 20, as at 27, the stepping of this rim providing bearing shoulders 28, 29, respectively.

Against the shoulder 28 the inner wall member 30 of the top wall rests, it having a short upstanding central flue 31 provided with an outstanding flange 32, the up er face of which latter is in line with the s oulder 29 of the rim 26. Resting upon said flange and shoulder 29 is an intermediate wall member 33 formed of asbestos and separated from the wall 30 by an intervening dead air space 34. 35 is the outer wall member of the chambered top and at its marginal portion rests upon the upper edge of the rim 26. This outer wall member has a central opening with a depending flange 36 which rests .upon the asbestos intermediate wall member 33, the latter being separated from the outer wall member 35 by an intervening air space 37. The short central flue of the inner wall member 30 of said chambered top passes through the central opening of the top wall member 35 and an escape or draft stack 38 is fitted onto the upper end of said short flue. Flue 31 may be considered as forming part of said stack and it has a series of perforations 39 which register with notches 40 formed in the depending flange 36 of wall member 35. Through the shouldered portion 29 of the rim 26, air openings 41 are provided which place the air space 37 in communication with the outer air chambers 22 of the side and rear walls so that the air entering said chambers through the inlets 24 passes upwardly through the openings 41, thence through the notches 36 and apertures 39 and finally escapes through the stack 38. This air keeps the exterior of the casing cool and tends also, in the event of the furnace being improperly operated, to mingle with any slight odors or traces of gas escaping from the interior so that these become unnoticeable as they escape from the upper end of the stack.

The space 34 is a dead air or insulating chamber, and with the asbestos wall 33 serves to keep the top of the casing cool.

42 designates the grate between which and the bottom wall 15 an ash pit is arranged. In the latter a pan 44 may be removably placed which is adapted to receive the ashes of the burned refuse. Situated above said grate, which is preferably of the shaking type, is aburner 45 of conical formation in cross section. This burner is hollow and provided at opposite points with laterallyprojecting gas-escape tubes 46 and it has numerous perforations 47 formed therein. 48 designates gas supply pipes which are passed through the front of the incinerator and terminate within theconical burner 45, these supply pipes having their outer ends connected to a gas feed pipe 49 and their inner ends are directed laterally in line with the gas-escape tubes 46, as at 50. Any other burner suitable for the purpose intended may, however, be substituted.

An auxiliary gas supply pipe 51 is provided which enters the incinerator through the front wall of the same, and has two laterally-disposed branches 52 which terminate adjacent the inner extremities of the gas supply pipes 48, these branches 52 being used as pilot lights to light the gas escaping from the pipes 48 within the burner when gas is fed thereto. The burner is' mounted on bars 53 fastened in any suitable manner to the front and rear walls, respectively, of the casing.

The inner wall members 20 are provided with vertical fiues 54 which terminate at their lower ends in line with the gas-escape tubes 46 of the burner and at their upper ends a distance below the chambered top of the casing, both ends being open. The upper ends of these flues communicate with a concentrator 55 which forms the top wall of the refuse chamber and is separated from the chambered topwall of the casing by a space 56 serving as an auxiliary combustion chamber. This concentrator comprises a chambered or channeled wall formed by a plate 57 supported in a manner to be presently described; a plate 58 situated above plate 57 and spaced therefrom, and a plate 59 situated above plate 58 and spaced therefrom, said plates having register openings 60, 61, 62, respectively, which form a restricted passage to be considered, in a broad sense, as a primary combustion chamber. The plate 58 receives support from plate 57 while the plate 59 receives support from plate 58. The manner in which the plate 57 is supported is by means ofr'lugs 63 extending from the fines 54, said plate being provided with notches 64 at its side and rear marginal portions through which the fiues 54 extend. Said plate has also upstanding spacing flanges 65 which are preferably L- shaped to provide converging air passages 66 that lead to a central expansion chamber 67, said passages being in communication with the inner air chambers 23 of the side and rear walls by openings 68 which are arranged in the inner wall members 20 at opposite sides of the flues 54.

Each of flues 54 has a series of apertures 54 at its lower end, through which part of the upwardly traveling flame passes to attack the refuse at the sides.

The expansion chamber 67 merges into the primar combustion chamber formed centrally 1n the concentrator. The flues 54 have their upper ends terminating flush with the upper surface of plate 58 which rests upon the upstanding flanges 65 of plate 57 and plate 59 is provided with depending spacing flanges 69 arranged to provide diverging fire flues or passages 70 which con nect with the upper ends of the flues 54 and lead inwardly to the primary combustion chamber. This primary combustion chamber, opens into the auxiliary combustion chamber 56 and has preferably situated therein a retarder 71 in the form of a hollow cone open at its lower end and provided with a number of comparatively large airinlet openings 72 in registration wit-h the ex pansion chamber 67 of the concentrator. This retarder is also provided with numerous perforations 74.

The front end of the casing comprises an inner wall and an outer facing plate 75. Said wall and plate have suitable openings through which garbage or other refuse may be introduced into the incinerator and these openings also permit access to the burner and the ash pit and are provided with doors 78.

In operation the garbage or refuse is stored within the refuse receptacle as accumulated, and by reason of the air being allowed to circulate through the several passages and openings in the apparatus, the garbage or refuse is dried out dur1ng the storing period thereof prior to igniting the garbage or refuse. The garbage or other refuse deposited into the receptacle rests upon the grate 42 and also upon the burner 45, and upon turning on the supply of gas in the feed pipe 49 it is ignited at the extremities of pipes 48 by the pilot lights 52, the flames being directed through the gas-escape tubes 46 and entering the upright tubes 54 from which they escape and enter the top chamber or passages of the concentrator.

From these they enter the retarding hood through the openings 74 therein, the three flames impinging against each other and creating an intense fire. These flames meeting each other, spread across the hood and form a wall of fire within the hood. The burning gas also escapes through the numerous perforations 47 of the burner and attacks the refuse. through the flues 54 escape in part through the apertures 79 in said flues and attack the refuse at the sides. Ordinarily when burning a batch of green garba e or refuse, a heavy dark smoke is create and ofi'ensive gases generated. This smoke and the gases must pass up through the primary combustion chamber which the retarding hood, when used, must be considered as forming, and in their upward passage meet the cross currents of heated air entering the retarding hood through the openings 72. These cross currents of heated air temporarily check the smoke in its travel and allow the lighter gases contained therein to separate. A combustion is thus caused which is promoted by the flame directly above. This promoted combustion assists in consuming the smoke, the unconsumed smoke and products of primary combustion in passing upwardly through the hood being intercepted by the wall of fire spanning-the retarding hood and being completely burned; thus insuring the consumption of all gases and smoke. Although this action may be carried out without the use of the retarding hood, the latter is intended to check or retard the passage of the smoke through the concentrator. Said retarding hood is adapted to battle excess smoke and the wall of fire therein creates an agitation of the smoke so that it is thoroughly mixed with the heated air before it passes into the fire.

In the auxiliary combustion chamber the final purification of any smoke that may escape the primary combustion chamber will take place. The intense heat created in the primary combustion chamber escapes eventually to the auxiliary combustion chamber, but this intense heat is not imparted to the top wall of the casing, since insulation is provided by the dead air chamber 34, the fresh air space 37 therein andthe asbestos intermediate wall member 33. The passage of air through the apparatus, as above described, prevents smothering of the fires or burners, and as constructed, the flames from the burner reach the concentrator through small concentrating upright fiues or channels 54 at the sides and back so that the flames are confined and carried to a considerable distance. These flues also become highly heated and burn channels through the garbage around the flues through which the flames from the burner can work.

Under the principle involved, the construction herein disclosed may be variously modified without departing from my invention or sacrificing any of the advantages of my invention.
